I also started a discussion here: http://stackoverflow.com/questions/26657597/different-matching-results-for-opencvs-descriptor-extractor-matcher-when-loadin I'm trying to match an image against a set of stored keypoints and descriptors. As described in the above link I get different results for these two cases:
If I am using SIFT and SURF there is no difference between the two cases, what is basicly what I would have expected, as I'm using in both cases the stored data. But if I use ORB, BRISK or other descriptors, I get different matching results! So using the descriptor_extractor_matcher.cpp sample (with some edits for reading and writing) it works well for
and it doesnt work for
I don't have a clue whats the difference between the two cases, and why there it is in addition working for some descriptors... ?! Thanks for your help! |
